Replaced NSS, now no reverse lights - PeachParts Mercedes-Benz Forum

Just as a precautionary measure, I replaced the Neutral Safety Switch. Everything seems to work fine as far as starting in Neutral and Park, but now there are no reverse lights. I noticed that on the aft side of the switch, it is possible to adjust the height up or down before tightening the 10 mm bolt that holds it on. I set the switch at the midpoint. Does anyone know which way the aft part of the switch should be adjusted (up or down) in order to get the reverse lights to work? I guess I have 50% chance of guessing right the first time.

Thanks.

Thanks to Deanyel and a certain expert on aux fans and a/c systems (he might be retired but apparently drops in often enough), I was able to adjust the NSS with no problems.

Attached are some pictures. The first two are of my old NSS showing the hole that needs to be aligned with the lever and the NSS casing. The second two are the new switch on the vehicle. All it took was putting the car in neutral, loosening the two 10 mm mount bolts on the NSS and moving the NSS until I could get the 4 mm Allen wrench to align with the two holes. Now the reverse lights work fine. Thanks guys!
